STS301L 가스용접이음재의 가속수명에측에 관한 연구 (1. Plug and Ring type)
A study on Accelerated Life Prediction of Gas Welded joint of STS301L (1. Plug and Ring type)
초록
Stainless steel sheets are widely used as the structure material for the railroad cars and the commercial vehicles. These kinds structures used stainless steel sheets are commonly fabricated by using the gas welding. Gas welding is very important and useful technology in fabrication of an railroad car and vehicles structure. However fatigue strength of the gas welded joints is considerably lower than parent metal due to stress concentration at the weldment, fatigue strength evaluation of gas welded joints are very important to evaluate the reliability and durability of railroad cars and to establish a criterion of long life fatigue design. In this paper,
